Simple interest means an portion of the principal is added to the principal. In this case the 6% simple interest is will be only from the principal amount which is $800.
A. The finance charge or the interest is $48 ( 6% of $800). B. The total amount to be repaid is $800 (principal amount) + $48 (6% interest) = $848. C. To equally pay off the total amount every month, we simply divide $848 by 8 months. $848 / 8 months = $106. The monthly payment would be $106.
Let l and l-6 be the length and width, respectively, of the rectangle. Then: l(l-6)=40 l²-6l-40=0 (l-10)(l+4)=0 l=10,-4 The rectangle is 10" by 4". ☺☺☺☺
